If the offline code is being installed on a machine without the
old FORTRAN based Labyrinth package installed on it
then the B-field maps shared by both must be installed in order to
do muon momentum fitting. If the Labyrinth is installed
then the normal setup for that should define the BMAPPATH
environment variable that points to the appropriate place.
This additional installation step will need to be done until the
offline BField package has been converted to get the map
information from the database (and the database is populated).
The simplest means of getting the datafiles is to use cvs
to check out a copy:
$ cd some-path
$ cvs -d $CVSROOT checkout bmaps
Then the only requirement is that one must define the environment
variable BMAPPATH to point at some-path/bmaps.
This can be done at any point before the start of the loon
job; but it is probably most convenient to do it in the site setup
script (usually found in
